Abstract
The utility model relates to a roller stabilizer self -lock device, including being equipped with the stabilizer main part of centre bore, the equipartition has the arch unanimous with stabilizer modal length direction three at least on the stabilizer main part lateral wall, has seted up the dovetail along stabilizer length direction on the protruding lateral wall, spool is equipped with the forked tail spindle nose through the round pin in the dovetail, it is parallel to each other and is used for installing the shaft hole of roller shaft to set up axle center and centre bore axle center in the forked tail spindle nose. The utility model discloses the equipartition has the arch unanimous with stabilizer modal length direction on stabilizer main part lateral wall, follows stabilizer length direction on the protruding lateral wall and has seted up the dovetail, and the forked tail spindle nose is installed in the dovetail through the round pin axle, and round pin axle prevention forked tail spindle nose slides along the dovetail for this device forms a firm whole, and it provides safeguard to work for the drilling string is normal.
Description
Technical field
The utility model relates to well drilling tool field, is specifically related to a kind of roller stabilizer self-locking device.
Background technology
At present in wellbore construction process, underground drill stem will access drilling string stabilizer instrument, wherein one is roller stabilizer, along with the rotation of drill string, roller on roller stabilizer is righting drill string while rotating, but the Roller Shaft locking on roller stabilizer is pressured piece of bolt, its fragile fall well, and not easy-maintaining.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of roller stabilizer self-locking device, and it is firmly overall, good stability.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of roller stabilizer self-locking device, comprise the stabilizer body being provided with centre bore, stabilizer body lateral wall is evenly equipped with at least three projections consistent with stabilizer body length direction, protruding lateral wall offers dovetail groove along stabilizer length direction, being equipped with dovetail spindle nose by bearing pin in dovetail groove, in described dovetail spindle nose, offering the axis hole that axle center and centre bore axle center are parallel to each other for installing roller shaft.
The cross section of described projection is trapezoidal.
Described dovetail groove two side is provided with the first pin-and-hole, offers second pin-and-hole relative with the first pin-and-hole in dovetail spindle nose, described bearing pin to penetrate in the first pin-and-hole and the second pin-and-hole thus is fixed in dovetail groove by dovetail spindle nose.
The utility model is evenly equipped with the projection consistent with stabilizer body length direction on stabilizer body lateral wall, protruding lateral wall offers dovetail groove along stabilizer length direction, dovetail spindle nose is arranged in dovetail groove by bearing pin, bearing pin stops dovetail spindle nose to slide along dovetail groove, this device is made to form a firmly entirety, ensure that this device is working properly, provide safeguard for drill string normally works.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of roller stabilizer self-locking device, comprise stabilizer body 1, centre bore 2 is provided with in stabilizer body 1, stabilizer body 1 lateral wall is evenly equipped with at least three projections 3 consistent with stabilizer body length direction, protruding 3 lateral walls offering dovetail groove 4 along stabilizer length direction, in dovetail groove 4, is equipped with dovetail spindle nose 6 by bearing pin 5, in dovetail spindle nose 6, offering the axis hole 7 that axle center and centre bore axle center are parallel to each other for installing roller shaft.
Protruding cross section is trapezoidal, and certain protruding lateral surface can be also arc, makes protruding lateral wall corresponding with bore hole inside wall, avoids projection and drilling well contact internal walls to rub.
Dovetail groove two side is provided with the first pin-and-hole 8, second pin-and-hole relative with the first pin-and-hole is offered in dovetail spindle nose 6, bearing pin 5 to penetrate in the first pin-and-hole and the second pin-and-hole thus is fixed in dovetail groove by dovetail spindle nose, bearing pin 5 slides along dovetail groove for stoping dovetail spindle nose 6, makes this device form a firmly entirety.
When the utility model uses, this device is enclosed within drill string by centre bore 2, and Roller Shaft and dovetail spindle nose 6 are locked in stabilizer body 1 by bearing pin 5, and dovetail spindle nose 6 cannot be slided along dovetail groove, ensures that roller is installed firmly.After this device goes out well, if when the damage of roller stabilizer needs to repair, take out bearing pin 5, exit dovetail spindle nose 6, the roller that just can more renew and Roller Shaft, the roller stabilizer after reparation can enter well again.The utility model is suitable for the self-locking of Roller Shaft in the drill string roller stabilizer in the drilling wells such as oil, geology, the hydrology, colliery, improves the stability of roller stabilizer in down-hole, avoids the dovetail spindle nose on roller stabilizer to fall well.
